RESUMO:

This work evaluated the physical-chemical parameters of water, ectoparasite prevalence, haematological characterization and zootechnical performance of Nile tilapia (O. niloticus), grown in three different culture systems in the Tubarão Region. The systems were evaluated: system 1: integrated with swine (using the total manure), system 2: integrated with swine (using the solid part manure) and system 3: without integration with swine breeding (extensive system). Initial stocking densities were 3.05 ± 0.11; 3.59 ± 0.47 and 1.09 ± 0.54 fish.m-2 in systems 1, 2 and 3, respectively. Hematological and parasitological analyzes of 90 fish per production system. Silica and phenol were higher in the total waste system (p <0.05). Nitrogen compounds (ammonia, N-nitrite, N-nitrate) were significantly lower in the extensive system (p <0.05). The temperature, dissolved oxygen, pH, alkalinity, sulfide and total iron did not present a significant difference (p> 0.05) between the culture systems. The prevalence of trichodyne was higher in the gills of the fish in the system with solid waste, while the prevalence of monogenea was higher in fish gills of the total system (p <0.05). Neutrophils were present in a greater number (p <0.05) in the extensive system. Thrombocytes, lymphocytes and monocytes in less volume in the system with total waste (p <0.05). No difference was observed in the mean hematocrit, erythrocyte, basophils, eosinophils and CGE between the systems. The final weight, mean productivity and survival rate were lower in the extensive system (p <0.05). There was no difference in daily weight gain between the cultures. The solid waste system presented a reasonable infestation of ectoparasites, not compromising hematological parameters, obtaining the best production indexes, making it the most efficient from the environmental and zootechnical point of view for the Tubarão region.
